Speedline Fast 10

  - Adams
As with the entire Speedline brand, the patent-pending aerodynamic shaping of the third-generation FAST 10 driver refines the technology to create 10 percent less drag and airflow turbulence than previous models, resulting in up to 15 yards more yards of carry distance. Design improvements include a 100 percent increase in toe curvature and a 300 percent decrease in the heel curvature for even more efficient and stable airflow attachment around the club head.
